Oil Pressure Gage Display

The Oil Pressure Gage Display shows the engine operating oil pressure. This signal is supplied to the Cluster through the TAN (31) wire. With low oil pressure, the sender resistance is low. With high oil pressure, the sender resistance is high.

If engine oil pressure drops below 69 kPa (10 psi), a box around the Oil Pressure Gage ISO Symbol flashes to indicate low oil pressure.
